Add WASM bindings for Solana transaction parsing and inspection: - Transaction.fromBase64() / fromBytes() for deserialization - Access to fee payer, recent blockhash, account keys - Instruction decoding with programId, accounts, and data - AccountMeta with isSigner/isWritable flags - Signature access by index (base58 or bytes) - Signable payload extraction for verification Add parseTransaction() for semantic instruction decoding: - Decodes System Program: Transfer, CreateAccount, NonceAdvance - Decodes Stake Program: Delegate, Deactivate, Withdraw, Authorize - Decodes ComputeBudget: SetComputeUnitLimit, SetPriorityFee - Decodes Token Program: Transfer, TransferChecked, CloseAccount - Decodes ATA Program: CreateAssociatedTokenAccount - Decodes Memo Program - Output format matches BitGoJS TxData interface BitGoJS compatibility tests verify identical output for: - Transfer with memo and durable nonce - Multi-transfer transactions (6 recipients) - Staking activate transactions - Token transfer transactions - Simple unsigned transfers Uses official Solana crates exclusively: - solana-transaction for Transaction type - solana-system-interface for SystemInstruction - solana-stake-interface for StakeInstruction - solana-compute-budget-interface for ComputeBudgetInstruction Removed ed25519-dalek dependency (-44KB WASM, -36KB gzipped). Replaces @solana/web3.js Transaction.from() in BitGoJS. Ticket: BTC-2929
Add interactive UI for parsing and inspecting Solana transactions: - Accepts base64-encoded transactions (standard Solana wire format) - Shows fee payer, blockhash, and signature count - Detects and displays durable nonce information - Decodes known instruction types with color-coded display - Supports URL param sharing for easy transaction sharing Issue: BTC-2929 Ticket: BTC-2929
